tools and accessories. (e.g.5 valve manifold). 5. CONSTRUCTION AND FUNCTION 5.1 Overview 1 - Sensing diaphragm 2 - Sealing/spring bellows 3 - Connecting rod 4 - Pointer mechanism 5.2 Description of function The pressures to be compared, differential pressure, act on a flexible stainless steel diaphragm, which separates the two pressure chambers.the diaphragm is mechanically linked by a rigid connecting rod. When pressures are equal on both sides, the diaphragm is on zero position. When there is a difference in pressures the diaphragm is deflected away from the high pressure side, towards the lower pressure side, causing a displacement of the connecting rod. A precision mechanism translates the linear displacement of the diaphragm connecting rod to angular movement of the gauge s dial pointer. The pointer s displacement range of 270 corresponds to the full scale differential pressure. 5.3 Description of components 5.3.1 Scale with pointer The differential pressure gauge is equipped with a dial face and pointer pursuant to DIN 16003, nominal size 100 mm or 160 mm. 5.3.2 Instrument connection The instrument connection is located on the underside of the differential pressure gauge and can be male or female threaded process connection. Distance between ports is 37 mm, please consider this when selecting a 5 valve manifold. 5.3.3 Vent plug The vent plug for the housing is located on the top of the gauge case. If the nipple is pulled out, the housing is vented and the pressure which has built up in the housing due to the influence of temperature is discharged. With the plug closed, protection class IP 66 is achieved. 5.3.4 Rear wall/plug with blow-out capability The pressure gauge has a plug capable of blowing out on the rear wall of the housing (Model F5509) or a rear wall capable of blowing out (Model F6509). These act as a safety feature pursuant to DIN 16003 and simultaneously allow for temperature compensation for the housing, via a rubber membrane 5.4 Accessories Please contact the manufacturer regarding available special 6 TRANSPORT 6.1 Safety The pressure gauge should be protected against the effects of knocks and impacts. The device should only be transported in the packaging provided, to protect against glass breakage. The device should only be transported in a clean condition (free of residues of measuring media). 6.2 Transport inspection The delivery must be checked for completeness and damage during transport. In the event of damage during transport, the delivery must not be accepted, or only accepted subject to reservation of the scope of the damage being recorded and, if necessary, contact Ashcroft for instructions. 6.3 Storage The differential pressure gauge must be stored in dry, clean conditions, within a temperature range of -20 to +80 C, protected against direct exposure to sunlight and protected against impact damage 7 ASSEMBLY/INSTALLATION 7.1 Safety To ensure safe working during installation and servicing, suitable shut-off valves must be installed in the plant (see 5.4 Accessories), enabling the device: To be depressurized or taken out of operation; To be disconnected from the pressure source for repair or inspection; Or to enable function tests of the device to be performed on site. During the works to mount/install the gauge, the plant must be protected against being switched back on. 7.2 Preparations (requirements for the installation location) A check on suitability of the device for the medium to be measured, the scope of the measurement range and static pressure and of the protection against special conditions such as vibration, pulsation and pressure spikes. A bracket must be installed to support the pressure gauge if the mountering process pipe is not able to provide adequate support. The installation location should be chosen such that the work-spaces for operating personnel are not located to the rear of the pressure gauge. 7.3 Mounting/Installation 7.3.1 Process connection The instrument is intended and factory adjusted for vertical mounting, pressure ports downward. When mounted in other orientation (max. ± 10 ) the pointers zero position needs to be adjusted (see 7.4.1 Zero point adjustment). Connection to be made by authorized and qualified personnel All sales subject to standard terms and conditions of sale. F5509_gauge_im1.0, Rev. A, 08/18 3
only. Use only with the mechanical process connection provided regarding the configuration, see order code on the device type label, with a matching threaded seal. When connecting the device, the process piping must be depressurized. The process pipe must be installed on an incline so that: -for fluid measurement, no air pockets are created -for gas measurement, no water pockets are created If the necessary incline is not achieved, then at suitable points water separators or air separators must be installed. The pressure process pipe must be kept as short as possible and installed without sharp bends, to avoid a delayed response time. The instruments pressure ports are marked by + and - symbols: + port must be connected to the higher pressure - port must be connected to the lower pressure. With liquid measurement media, the pressurized connection pipe must be degassed, since any gas bubble inclusions result in measurement error. If water is used as the measurement medium, the device must be frost-protected. 7.3.2 Electrical connection Safety notice: Only mount using the correct open-jawed wrench, and do not twist the device itself. Connection to be undertaken by authorized and qualified specialist staff only. The electrical connection of the device is to be undertaken in accordance with the relevant regulations of the VDE and the regulations supplied by the local utilities company. Disconnect the plant from the main supply before wiring electrical connections. Install appropriate fuses upstream. Switch 1 Switch 2 7.4 Starting up The precondition for start-up is proper installation of all electrical feed lines and metering pipes. All connecting lines must be installed so that no mechanical forces can act on the device. Before start-up, the seal on the pressurized connection line must be checked. 7.4.1 Zero point adjustment The pressure gauges are supplied calibrated at the factory, so that as a rule there is no need for calibration at the installation point. For devices with Micrometer pointer (see. order code), zero pointer adjustment on site is possible. For this, proceed as follows: Equalize pressure in both chambers. Check if internal pressure was built up in the case due to ambient temperature effect. Open valve (position B), wait for pressure relief and close valve again (position A) Lift up on vent plug. Use zero pointer adjustment screw to set the pointer to zero. Mount vent plug Filled Models need to be vented before commissioning by opening the air valve on the upper side of instrument! 7.4.2 Setting the electric contacts An adjustable lock is fitted in the front panel of the pressure gauge. Using the removable adjustment key, the contacts mounted on the target value indicators can be set to any point on the range covered by the scale. For reasons relating to accuracy of switching and the lifetime of mechanical measurement systems, the switch points should be positioned between 10% and 90% of the range. Place the adjustment key on the axle of the adjustable lock. Press the axle inwards, until the carrier arm grips behind the adjuster pin on the target value indicator. By turning the key, adjust the target value indicator to the desired switch point. All sales subject to standard terms and conditions of sale. F5509_gauge_im1.0, Rev. A, 08/18 4
Release the pressure on the axle, and remove the adjustment key. 7.4.3 Contact function Function 1: Close contacts with the indication rising in a clockwise direction. Function 2: Open contacts with the indication rising in a clockwise direction. Contact assignment: 1st contact left target value indicator, 2nd contact middle target value indicator, 3rd contact right target value indicator 7.5 Subsequent relocation of the gauge (by the customer) Recommendation: Do not remove the pressure gauge from one pressure monitoring location to another, as there is a risk of the process media being mixed, with unforeseeable chemical reactions. 8 SERVICING The device is maintenance-free. However, to ensure reliable operation and a long lifetime for the device, we recommend that it is checked regularly. 8.1 Safety When servicing the pressure gauge, the process lines must be depressurized. Special attention should be taken to ensure process pressure is not applied. 8.2 Gauge performance and calibration Gauge performance and recalibration should be checked at regular intervals, depending on the application. The precise testing cycles should be adjusted in line with the operating conditions and ambient conditions. In the event of various device components interacting, the operating instructions for all other devices should also be taken into account. Check on display. Check on function, in conjunction with downstream components. Check of pressurized connection pipes for seal condition. Check of electrical connections 8.3 Cleaning and maintenance Cleaning is carried out using a non-aggressive cleaning agent, with the ventilation valve closed and respecting the protection category of the device. 9 WHEN ACTION IS REQUIRED TO REPAIR/REPLACE THE GAUGE 9.1 Safety Defective or faulty pressure gauges put the operational safety and process safety of the plant at risk, and can lead to a risk or injury to persons, the environment or the plant. 9.2 Conduct in the event of failure All defective or faulty gauges must be taken out of service.
